Method Detail


public java.lang.Object propertyNameToKey(java.util.Map values,
                                          java.lang.String propertyName)
Returns a key object of Map corresponding to propertyName. Return null if there is no key object appropriate for propertyName. In this case, BeanHandler tries to invoke Map object's accessor method rather than to call its get/put method. If it doesn't have a corresponding accessor method, IllegalArgumentException would be thrown.

values - A Map object containing properties of the bean. You can use this Map to find out a key of Map corresponding to the propertyName. Don't change this Map.
propertyName - A name of property.
A key object of Map corresponding to propertyName, or null.
